Since writing about the features of the Catalyst 14.6 Beta earlier today, the x86/x86_64 proprietary Linux driver has surfaced on a third-party web-site for those wishing to try out this latest AMD Linux graphics driver.

Besides AMD's R9 290 "Hawaii" open-source support being broken and still not working right even after the hardware has been available to consumers for a half-year, with the Linux 3.15 kernel there's also problems right now for those with newer AMD Radeon GPUs.

While the AMD Hawaii open-source is broken, at least for older "GCN" era graphics cards supported by the RadeonSI Gallium3D driver the performance is starting to match -- or even exceed -- the proprietary Catalyst Linux graphics driver.

While AMD's Radeon R9 290 "Hawaii" graphics cards have been out on the market for more than a half-year, the open-source driver support still isn't working quite right when it comes to having GPU hardware acceleration.

After getting the small Radeon DRM changes queued for Linux 3.15, AMD developers have gone ahead and merged their open-source AMD Mullins graphics driver support into the DRM library (libdrm), xf86-video-ati DDX, and Mesa.
